我最近偶然发现了和你一样的问题。我不确定现在帮助你是否已经太晚了，但我仍然会为我提供解决问题的方法 我不知道您的全部代码，所以我不能确定它是否与您的问题相同，但我也尝试绑定一个列并在以后编辑它，导致相同的崩溃 其实很简单。在将列添加到大纲视图之前，我绑定了该列，如下所示：
[theEditingColumn bind:@"value" myTreeController withKeyPath:[NSString stringWithFormat:@"arrangedObjects.%@", metadata.columnBindingKeyPath] options:bindingOptions];
[theOutlineView addTableColumn: theEditingColumn]
[theOutlineView addTableColumn: theEditingColumn]
[theEditingColumn bind:@"value" myTreeController withKeyPath:[NSString stringWithFormat:@"arrangedObjects.%@", metadata.columnBindingKeyPath] options:bindingOptions];
@stevesliva你确定这只是异步调用的问题吗？我得到一个“unregonizedselector”异常：它调用代理上的getter，而不是其内容。否。可能不仅仅是这样。只会使调试复杂化。当你只有一把锤子时，一切看起来都像钉子。。。只要把它扔出去，如果对您的情况没有结果，很乐意删除。
